World’s most integrated one-chip solution

Cypress Semiconductor has introduced the latest series from its PSoC 4 programmable system-on-chip architecture. The PSoC 4 L-Series is said to be the industry’s most integrated single-chip solution with a 32-bit ARM-Cortex-M0 core, featuring up to 256KBytes flash memory, 98 general purpose I/Os, 33 programmable analogue and digital blocks, a USB device controller, and a control area network interface.

The PSoC 4 L-Series is suited for industrial and consumer applications, leveraging the flexibility of the PSoC architecture to address multiple product variations and Cypress’s CapSense capacitive touch-sensing technology to implement reliable and elegant user interfaces.

John Weil, vice president of MCU marketing at Cypress, said: “The PSoC 4 L-Series introduces capabilities such as dual-mutual CapSense blocks with up to 94 channels for large, capacitive-touch home appliance applications and USB and programmable digital blocks to create bit-perfect digital audio solutions. Additionally, it provides all the resources needed to create new products for the emerging USB Type-C market.”

The PSoC 4 L-Series delivers up to 13 programmable analogue blocks including four high-performance opamps, four current-output digital-to-analogue converters, two low-power comparators, a 12-bit SAR ADC and dual CapSense blocks with up to 94 capacitive-sensing channels. The programmable analogue blocks are said to enable engineers to create on-chip, custom analogue front ends to support end-product features, without increasing product costs, size or power consumption.

The PSoC 4 L-Series delivers up to 20 programmable digital blocks including eight timer/counter/PWM blocks, four serial communication blocks and eight Universal Digital Blocks (UDBs). UDBs can be configured as coprocessors to offload compute-intensive tasks from the ARM Cortex-M0 core. The blocks are also said to enable engineers to implement custom digital peripherals, state machines or glue logic.

The PSoC 4 architecture is complemented by the PSoC Creator Integrated Design Environment (IDE), which is claimed to simplify system design and accelerates time-to-market by enabling concurrent hardware and firmware design.

The PSoC 4 L-Series will be available in 48-pin TQFP, 64-pin TQFP, 68-pin QFN and 124-pin VFBGA packages.
